weight/resistence =distance or something

The maximum velocity an object reaches will be its speed directly before it hits the ground, regardless of how far it falls.

Like Anonymous said - all the way to the bottom. There is speed called "Terminal velocity" which is the point at the upward force due to resistance is equal to the gravity force downwards. But a falling body never reaches its terminal velocity, it inches closer and closer to it without ever reaching it, following a inverse exponential law.

Consider an object falling from space. Initially there is no atmosphere to slow the object so it will accelerate under gravity without being slowed. Right up to the point before the object encounters any of the earths atmosphere it will keep accelerating. As soon as it hits the atmosphere it starts to slow down. And as the atmosphere gets denser it slows even more. So the answer is that an object will reach its terminal velocity and there after start to slow down in proportion to the atmospheric density it encounters. A good example was when Joe Kitzenger jumped out of a high altitude balloon. Due to the extremely thin atmospher he jumped out into, his initial terminal velocity was reached with in a few seconds and was recorded at nearly 600mph ! From that point onward he obviously started to slow down as the air got 'thicker' and slowed him down to a typically speed of a man in free fall of about 130mph. The same thing happens to an object dropped off a building only on a smaller scale of velocity variation. Hope this helps.
